I read the book years ago and yes, those are the two authors, although I can't confirm the exact spelling of their names. I recall that one of the authors was a French journalist and one a nuclear scientist of some kind. At the time, when I read it, I was facinated with what the book had to say but then I'm the kind of guy who read the Anarchist's Cookbook and other weird offerings during the 60s and 70s. Anyway, they did write another book- a kind of followup to "Morning" that was so forgetable that I've forgotten what it was about! Still, I would like to read "Morning" again, but I lent out my copy decades ago to someone who never returned it and the book is now out of print and now, generally unavailable.
